Q1Which cellular organelle is primarily responsible for calcium sequestration in odontoblasts during dentin formation?
Show answer
✓ Correct answer: Endoplasmic reticulum
The endoplasmic reticulum is the primary organelle responsible for calcium sequestration in odontoblasts during dentin formation. It helps regulate intracellular calcium levels critical for the mineralization process in dentin development.
Q2Which molecular process is most directly involved in the initial mineralization of dental enamel?
Show answer
✓ Correct answer: Nucleation
Nucleation is the initial process in enamel mineralization where the first calcium phosphate crystals form on the organic matrix, serving as sites for subsequent crystal growth during amelogenesis.
Q3Which cell junction type is most abundant in the junctional epithelium of the gingiva?
Show answer
✓ Correct answer: Desmosomes
Desmosomes are the most abundant cell junction type in the junctional epithelium of the gingiva. They provide mechanical strength to maintain the epithelial attachment to the tooth surface under mechanical stress.
Q4Which protein is the primary structural component of dentin?
Show answer
✓ Correct answer: Type I collagen
Type I collagen is the primary structural protein of dentin, making up approximately 90% of the organic matrix and providing the scaffold for mineralization.
Q5Which signaling molecule plays a crucial role in epithelial-mesenchymal interactions during tooth development?
Show answer
✓ Correct answer: Bone morphogenetic proteins (BMPs)
Bone morphogenetic proteins (BMPs) are critical signaling molecules that mediate epithelial-mesenchymal interactions during tooth development, influencing tooth morphogenesis and differentiation of odontoblasts.
Q6What is the primary molecular mechanism by which fluoride inhibits dental caries?
Show answer
✓ Correct answer: Enhancing remineralization of early carious lesions
Fluoride primarily inhibits dental caries by enhancing remineralization of early carious lesions through the formation of fluorapatite, which is more resistant to acid dissolution than hydroxyapatite.
